Protocols

A protocol describes the methods that will be used to conduct a systematic review, rapid review, or evidence scan, including an analytic framework, inclusion and exclusion criteria, and a synthesis plan (only for systematic and rapid reviews), which are tailored to the question.

Looking for more information about the 2025 Dietary Guidelines Advisory Committee? For more information about their work, including protocols for food pattern modeling and data analyses, please visit DietaryGuidelines.gov.

The public is encouraged to submit written comments to the 2025 Dietary Guidelines Advisory Committee on topics relevant to its work, including on its protocols. Learn more about submitting comments.

NESR protocols are made publicly available through posting on this page. More information about NESR’s methodology for developing protocols is available in our methodology manual.

The table contains all NESR protocols developed since January 2023. The “date posted” column shows when the protocol was originally posted to this website and the “status” column shows when the protocol was most recently updated. When a review has been completed, the protocol will remain posted to this website, and a link to the website with the completed review will be provided (“View Complete Review”).
